After completing the fourth planet (Menahut) you obtain the card input machine. Select Constellations (for Spectrobes) and enter the 9 digit sequence on the far left next to the desired Spectrobe. After that, click on the stars in the order described next to the code. 1 is the star furthest to the left, 2 is the next furthest to the left and so on. If there are 2 stars with the same horizontal position, A is the higher, and B is the lower. CT-01 through CT-05 are secret Spectrobes (those only obtainable through cards). CT-06 through CT-18 are evolved Spectrobes (with alternate textures), and CT-19 through CT-21 are child Spectrobes (3 different textures of Komainu) . (Note: Don't evolve the special Komainus as the adult and evolved forms look normal.)
